WEFT-REPLENISHING LOOM.

Specification of Letters Patent.

Patented Mar. 3, 1914.

Application filed I une 8, 1912. Serial No. 702,030.

To all whom it may concern Be it known that I, HORACE VrarAN, a citizen of the United States, residing at lVorcester, in the county of W'orcester and State of ll'lassachusetts, have invented certain new and useful Improvements in Teft- Replenishing Looms, of which the following is a specification.

ving t My invention relates to automatic weft replemshing looms of the type shown and described in the Letters Patent, No. 1,030,748, in which a stationary magazine is used with four guide-ways or compartments for superposed bobbins or filling carriers, at one end of the loom, and shifting or change shuttle boxes at the other end of the loom, for shuttles with fillings of different colors or characters, which correspond to the filling in the coipartments of the magazine.

y invention more particularly relates to weft replenishing looms of the type referred to, for weaving blankets or similar fabrics, which have a border woven thereon, with filling ordinarily of three different colors or characters, and the center portion of the blanket plain, with a filling of one color or character.

The object of my invention is to im rove upon the type of weft replenishing ooms referred to, and more particularly to provide two sugplcmental or extra. com artments 'or gui e-ways in the magaz1ne,w 1eh have their lower openings leading to the same general discharge o ening, and holding and releasing devices or said extra comartments or gulde-ways, which release the Eobbins at the roper time, to deliver a. bobbin to the crad e or retaining support of one of the other compartments, although only a single one may be used if desired.

The magazine shown in the drawings is provided with three compartments, which hold bobbins or filling carriers of the same color or character for the plain' center portion of the blanket to be woven.

I have shown and described in this instance a magazine with six compartments or guide-ways for superposed bobbins or filling carriers; three of the compartments are termed primary compartments, and are used for bob ins or filling carriers which have filling thereon which correspond with the filling inthe three change shuttles for weave border on the blanket or other fabric. The plain center portion of the blanket or other fabric is woven by the fourth shuttle, which has a bobbin with filling thereon which corresponds with the filling in the bobbins or filling carriers in the three other compartments or' guide-ways in the magazine. One of the three compartments, in this instance the fourth compartment of the magazine, is provided with the usual rocking cradle or support which releases the bobbin or filling carrier for its passage to the discharging end of the magazine, in the usual way. The two supplement-al or extra compartments or guide-ways are provided with retaining and releasing devices, which are adapted to release a bobbin and to deliver' the same to the cradle or support of the fourth compartment, after said fourth compartment has been emptied of its bobbins or filling carriers.

The cradle or rocking support is operated in the usual way to release a bobbin, which takes the place of the practically or substantially exhausted bobbin, with the same color or character of filling for the plain center portion of the blanket, in said shuttle, and said new bobbin is transferred into the shuttle bythe usual transferring mechanism.

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

I have only shown in the drawings a detached Vortion of the magazine of the class referre to, with my improvements combined therewith, sufficient to enable those skilled 1n the art to understand the construction and operation thereof.

Referring to the drawings-Figure 1 is an inner. end view of a detached portion of a magazme of the type referred to, with my improvements combined therewith. Fig. 2 isua plan view of some of the parts shown in Fig. 1, and a section, on line 2, 2, same figure, looking in the direction of arrow a, Fig. 1. Fig. 3 is a section, on line 3, 3, Fig. 2, ookin 1n the direction of arrow b, same figure; s owing the lower portion of the inner end of the magazine, with bobbins for the plain weave in their compartments. Fig. 4 corresponds to Fig. 3, but shows a different position of the rocking supports, and a bobbin dropped to the discharging end of the magazine. Fig. 5 is a section, on line I5, 5, Fig. 2, looking in the direction of arrow c, same fi ure, and showing the tips of the bobbins m their respective compartrods 3, the outer end 4 of the magazine, 'in' the usual way. The magazine basin this instance four vertically extending-:compartments or guide-'ways 2 for the'hea'dsof the bobbins 5, see'Figs. 3 and 4, andguide-ways 4' for the tips 5 of the bobbins 5,which have filling thereon corresponding in color or character to the filling on the bobbins inA the four change shuttles.

The magazine is provided in this instance with two supplemental or extra guide-ways or compartments 2a and 2", at the inner end of the magazine, and two compartments 4a and 4a', at the outer end of the magazine, as will be hereinafter described.

The bobbins 5 drop down by gravity to the lower discharging ends 2 and 4 of the magazine. Each of the four guide-ways or compartments of the magazine is provided at itslower end with mechanism for supporting the set of bobbins therein, and also for releasing the lowest bobbin'in each set, preparatory to its passage to the discharging end of the magazine to be transferred into the active shuttle.

The holding and releasing mechanism consists of a rocking support or cradle 6, pivotally mounted at the lower part of the magazine. A pin 6 extends within a curved slot 7 in the lower portion of the vertically moving bars 7, which are loosely guided at the end of the magazine 2. Each bar 7 is provided with two projections 7, which are adapted to extend in the path of and to be -operated by the lingers 8, which have their hubs 8- secured upon a horizontal sliding rod 9, which is loosely mounted in bearings 2 on the magazine 2. The end of said rod 9 has a collar 10 secured thereon, which has an annular groove l0', which is adapted to receive a stud on a lever, not shown, which, through the raising and lowering of the shuttle boxes on the o posite end of the loom, will communicate/t rough intermediate connections, not shown, a sliding motion to the rod 9 and to the lingers 8 thereon.'

The side extension 8 on the hubs 8, extends loosely into a notch on a lever 11, which, through its up and down movement, will im art a rocking motion to the extension 8' and the fingers 8, to cause the up and down movement of a vertically extending bar 7, and the rocking of a cradle 6.

h.All of the above mentioned parts, except t e may of any usual and well known conspeecial construction of the magazine,

I provide the stationary magazine, having' the our usual compartments or guide-ways, with two supplemental or extra compartments or guide-ways 2 and 2il for the heads 'of the bobbins 5, and 4a and 4" for the tips 5 of the bobbins 5, respectively, which b obbins, in this instance, correspond in color or character to the bobbins which are held by 4the .fourth compartment 24', and 4', respectively. The two extra compartments are vconnected at their lower ends, and are adapted to drop a bobbin 5 from each compartment into the same chute or incline, which leads the bobbins to the cradle 6,.which is adapted to retain, and to release the bobbins from the fourth compartmentlof the magazine in the usual way. The cradle 6 is operated in the usual way by the vertically moving bar 7, at the left in Figs. .1 and 2. Said bar is provided in this instance with a lug or ear 7, tol which -is pivotally connected the upper end of a downwardly extending connector 12; the lowerend of said connector 12 is pivotally connected to an arm 13, which has its hub13 secured on a transverse shaft 14, which, in this instance, is

loosely mounted in bearings 2 and 4 at the inner and outer ends 2 and 4, respectively, of the magazine. The transverse rod 14 has in this instance secured thereon retaining and releasing devices for the bobbins which are held in the supplemental or extra compartments or uide-ways of the ma azine. These retainlng devices consist int is instance of a lever 15 for 'the heads, and a lever 16 for the tips 5 of the bobbins 5, see

Figs. 3 to 6, inclusive. As clearly shown in the drawings, the shape of the levers 15 and 16 are so formed, that they are adapted to hold and to release the bobbins.`

The up and down movement of the vertically moving rod 7 will impart a rocking motion to the cradle 6, and also communicate at the same time a rocking motion to the devices or levers 15 and 16, which in one position, as shown in Figs. 3 and 5, will hold'the bobbins in their respective supplemental or extra compartments or guide-ways, and as the cradle 6 is rocked to drop a bobbin to the discharging end of the magazine, as shownf in Figs. 4 and 6, the devices 15 and 16 areV moved to theposition shown, coperating to release the bobbins 5 from their supplemental compartments.

If all of the bobbins 5 are dropped from the fourth compartment 2' and 4 the next bobbin from the supplemental compartment 4a. will takeits passage to the cradle 6, to

drop into said cradle, and` be delivered at the next movement thereof to the discharging end of-the magazine, until all of the bobbim are successively delivered to the cradle 6, and released therefrom in the usual Way, all as will be fully understood by those skilled in the art.

It will be understood that the details of construction of my improvements may be varied if desired.

Instead of the fourtlrcompartment, and the supplemental compartments being combined with other compartments for bobbins having fillings of different colors or characters, this fourth compartment, and the supplemental compartments are equally Well adapted to be used in'looms using one color only, andwithout the shifting shuttle boxes for shuttles with fillings of different colors, or the compartments of the magazine for bobbins of' corresponding colors. The fourth compartment, equally well with the other three, may be termed a primary compartment, in its combination with the supplemental compartments.

Having thus described my invention, What I claim as new and desire to secure by Letters Iatent is l. In a weft replenishing loom, a maga-zine having a primary compartment for superposed illing carriers, a rocking support or .cradle upon which the lowest of the superposed filling carriers rests, to retain said filling carriers, and also to release the lowest of said filling carriers from said compartment, and means for operating said support or cradle, and one ormore supplemental compartments for superposed filling carriers,

and retaining and releasing device for the filling carriers in said supplemental -eompartments, means for operating said retaining and releasing device, to allow the filling in a supplemental compartment to 40 pass into the adjoining primary compartment, upon the exhaust-ion of filling in said primary compartment.

2. In a weft replenishing loom, a magazine With for snperposed filling carriers, each compartment having filling of different colors or characters, retaining and releasing devices for said compartments, and one or more supplemental compartments for superposed filling carriers having lilling of the same color or character as the filling in one of said primary compartments, and retain-m ing and releasing devices for the filling carriers in said supplemental compartment or compartments, and means 'for operating said retaining and releasing devices, to allow the filling carriers in a supplement-al compartment to pass into the adjoining primary compartment, upon the'exhaustion of the .60

lling carriers in said primary compartment.
